Supply  
Connect all input and output terminals together (see Figure) before connecting the supply voltage. When testing, set the  
cut-off current to 1mA.  
Parameters Supply Device: Current limit set 1mA, Test voltage 1000Vdc, Test time 1sec.  
REPEATED HIGH-VOLTAGE ISOLATION TESTING  
A repeated high voltage test of a barrier component will degrade its isolation capabilities.  
The primary and secondary windings within this transformer are enameled (coated) but do not possess additional isolation.  
Typically, parts can withstand many times their stated test voltage and still perform optimally. The magnet wire coating can  
degrade over time due to chemical reactions that occur at high voltages. We recommend keeping high voltage isolation  
testing to a minimum to better protect the isolation between the windings. If repeated high voltage isolation testing is  
required, consider reducing the voltage by a significant amount e.g. 20% from the test voltage stated within the datasheet.  
These safety concerns are equally applicable to components that utilize functional isolation beyond wire coating (i.e.  
physical barriers or spacing).
